Abstract [en]

This report is the result of a diploma work made at Linköping University from August 2006 till September 2007 by Erik Lundin, under the guidance of Doctor Mike Andersson and Professor Anita Lloyd Spetz. Its purpose was to find suitable materials for the construction of an oxygen sensor. The hope was not to construct such a sensor, but to investigate materials that may be suitable in creating one. In the preparatory time period of the diploma work, different papers and books were studied in order to get a proper understanding of the sensor mechanism. During this period of time, a design proposal was made and the theory behind it is presented in this thesis. The main objective in this thesis has been to investigate the response of field effect devices to oxygen and other gases that are compounds in exhaust or flue gases. Devices were created by employing the materials which were investigated. Special material combinations were proposed for field effect devices suitable for oxygen detection by Doctor Mike Andersson. One material combination showed promising results for selective detection of the oxygen concentration in exhaust gases.
